Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain condition of road surface on which a vehicle does not yet run.SOLUTION: A road surface condition detection device 10 includes: a tire condition monitoring device 20; a car navigation system 41; a control unit 51 for controlling the tire condition monitoring device 20 and the car navigation system 41; and a transmitter 52 connected to the control unit 51. The tire condition monitoring device 20 has a sensor unit 21. A sensor unit controller of the sensor unit 21 estimates a road surface condition on the basis of an amount of change of a detection value detected by an acceleration sensor. The control unit 51 causes the transmitter 52 to transmit a road surface condition detection signal when there are crack and ruggedness on a road surface. A receiver 45 of the car navigation system 41 receives a road surface settling signal from a cloud server 61. 【課題】走行前の路面の状態を取得すること。【解決手段】路面状態検出装置１０は、タイヤ状態監視装置２０と、カーナビゲーションシステム４１と、タイヤ状態監視装置２０及びカーナビゲーションシステム４１の制御を行う制御ユニット５１と、制御ユニット５１に接続された送信機５２とを備えている。タイヤ状態監視装置２０は、センサユニット２１を有している。センサユニット２１のセンサユニットコントローラは、加速度センサの検出値の変化量から路面状態を推定する。制御ユニット５１は、路面に亀裂や凹凸が存在している場合、送信機５２から路面状態検出信号を送信させる。カーナビゲーションシステム４１の受信機４５は、クラウドサーバー６１から路面状態確定信号を受信する。【選択図】図１
